How to add a default include path for GCC in Linux?
提问by Jesse Beder
I'd like gcc to include files from $HOME/includein addition to the usual include directories, but there doesn't seem to be an analogue to $LD_LIBRARY_PATH.
$HOME/include除了通常的包含目录之外，我还希望 gcc 包含文件，但似乎没有类似于$LD_LIBRARY_PATH.
I know I can just add the include directory at command line when compiling (or in the makefile), but I'd really like a universal approach here, as in the library case.
我知道我可以在编译时（或在 makefile 中）在命令行中添加包含目录，但我真的很喜欢这里的通用方法，就像在库案例中一样。

Try setting C_INCLUDE_PATH(for C header files) or CPLUS_INCLUDE_PATH(for C++ header files).
尝试设置C_INCLUDE_PATH（对于 C 头文件）或CPLUS_INCLUDE_PATH（对于 C++ 头文件）。
As Ciro mentioned, CPATHwill set the path for both C and C++ (and any other language).
正如 Ciro 所提到的，CPATH将为 C 和 C++（以及任何其他语言）设置路径。

Create an alias for gcc with your favorite includes.
使用您最喜欢的包含为 gcc 创建一个别名。
alias mygcc='gcc -I /whatever/'

just a note: CPLUS_INCLUDE_PATHand C_INCLUDE_PATHare not the equivalent of LD_LIBRARY_PATH.
LD_LIBRARY_PATHserves the ld(the dynamic linker at runtime) whereas the equivalent of the former two that serves your C/C++ compiler with the location of libraries is LIBRARY_PATH.
只是一个注意事项：CPLUS_INCLUDE_PATH并且C_INCLUDE_PATH不等同于LD_LIBRARY_PATH.
LD_LIBRARY_PATH为ld（运行时的动态链接器）提供服务，而前两个为您的 C/C++ 编译器提供库位置的等价物是LIBRARY_PATH.
